From Wikipedia:
Nickel Plate Road #190 is a Morrison-Knudsen PA4 diesel locomotive rebuilt from an ALCO PA in 1975. Atchison, Topeka and Santa Fe Railway #62L was a PA1, sold to the Delaware and Hudson Railway (D&H) in December 1967. It is one of only two ALCO PA locomotives remaining in the United States.
The D&H renumbered it 18 and sent it to Morrison-Knudsen for rebuilding in 1975.
In 1978, this locomotive was sold to the Ferrocarriles Nacionales de México. Doyle McCormack obtained the wreck-damaged unit and brought it back the United States in 2000. Restoration began in 2002. McCormack chose to restore the locomotive as a Nickel Plate Road PA.
In 2012, the locomotive was moved to the new Oregon Rail Heritage Center, in Portland, Oregon.
